Good news. I have found an issue with the car.
Yesterday i cleaned the pcv? pipes that run from the bottom of then engine block and up back into the air intake. They looked a bit gungy. I had no change, but did run better.
Then today i have been thinking it through and decided to run my vag com on it. If you looked at all the measuring blocks, everything ran within the right specifications.
I then checked to see if there was any problems with the ignition system. There seemed to be power to and from the coil and was running fine again.
Car then cut out, as per normal, so decided to look and see if i was getting a spark. Found out i wasnt. I then re-checked the power into the coil and it was still there.
With having new leads, distributor cap and rotor arm i think there is a problem within the coil.
I am going to give it a go as soon as i can get one. Will let you know if it works
